Specification of Iletters Patent.

Patented Aug. 23, 1910.

Application filed October 30, 1909. Serial No. 525,511.

To all whom it may concern:

Be it known that we, JOHN BOVAIR and DANIEL RIEoKHorr, citizens of theUnited States, residing at Niagara Falls, in the county of Niagara andState of New York, have invented certain new and useful Improvements inHorseshoes, of which the following is a specification, reference beinghad therein to the accompanying'drawing.

This invention relates to horse shoe calks and has for its object toprovide an improved horseshoe calk.

The invention consists in an improved horseshoe calk and horseshoeconstructed and arranged as hereinafter set forth in the claim.

Figure 1 is a bottom plan view of the improved horseshoe. Fig. 2 is avertical sectional view thereof taken on the line 22, Fig. 1. Fig. 3 isa view in side elevation. Fig. 4. is a view in front elevation. Fig. 5is a detail perspective view of a toe calk used in connection with theimproved horse shoe. Fig. 6 is a detail fragmentary perspective view ofone of the heels for one of the shoes. Fig. 7 is a detail perspectiveview of a heel calk. Fig. 8 is a similar view of another heel calkadapted for preventing side-slipping of the shoe.

Referring to said drawings by numerals, l designates the body of theshoe, the toe 2 of which is provided with a central thickened pendentportion 3, which is provided with a central transverse recess 4, thesides 5 of which are inclined. An opening 6 is formed through the sidesof said groove t.

The heels of the body 1 are provided with pendent longitudinallyarranged oppositely disposed guard flanges 7, the inner surfaces ofwhich are inclined as indicated at 8. Said guard flanges of the heels aswell as the thickened portion 3 of the toe are on the under surface ofthe body L A transverse opening 9 is formed through the flanges 7 of theheels. As will be observed by reference to Figs. 36, the heels projectslightly beyond the outer ends of the guard flanges 7.

The improved toe calk comprises a flat body 10 having inclinedlongitudinal sides 11 adapted for a sliding engagement within the groove4, the inner end of said body be ing provided with an upstanding endflange 12 which is curved to conform to the contour of the inner edge ofthe body 1 and projects up to the plane of the upper surface of saidbody. The body 10 is provided with a transverse groove 13 which alineswith the opening 6, formed through the sides of the pendent portion 3 ofthe too 9. so that said body may be retained in rigid but detachableengagement with the groove 4 by means of the cotter pin 14:. The undersurface of the body 10 is provided with a calk 15 which is preferablysharpened. Said calk preferably extends well beyond each longitudinalside of said body 10 to provide an elongated gripping surface.

The heel calks have their body 16 provided with inclined sides 17adapted for a snug sliding fit between the guard flanges 7 of the heelswith their inner ends abutting the end walls 18 which close the spacebetween the inner ends of said flanges 7. Said body 16 is provided witha transverse opening 19 which alines with the opening of the guardflanges 7 so that the said body may be retained in rigid but detachableengagement by a cotter pin 20. The calk for the body 16 has an angularend 21 which abuts the outer end of said flanges 7 to limit the inwardmovements of said body. Said calks may have their gripping surfacetransversely arranged relatively to their body as indicated at 22 inFig. 7, or arranged parallel as indicated at 23 in Fig. 8.

It will be seen from the foregoing that the manner of fitting the bodiesof the calks within their grooves prevents relative vertical movement ofthe calks to the body, and longitudinal relative movement of said partsis prevented by the cotter pins which rigidly but detachably retain saidcalks in interlocking engagement with said body.

WVhat we claim as our invention A horseshoe formed with an enlargeddepending portion on the under side of the toe of the shoe provided witha central transverse recess having tapering sides, and transverse holesin said sides alining with each other, and a toe calk comprising a flatbody portion having longitudinal sides adapted for sliding engagementwith the transverse groove in the toe portion of the horseshoe, theinner end of said flat portion being provided with an upstanding curvedflange adapted to fit over the inner edge of the front portion of theshoe and the outer end of said flat portion being provided with atransverse groove, and having die In testimony whereof We hereunto afiixour pending therefrom a tapering calk, said signatures in presence oftwo Witnesses. oalk having its ends pro ect1ng beyond the JOHN BOVAIR.

sides of said fiat body portion, and a removable pin adapted to extendthrough said holes in the shoe and said groove in the Vitnesses: bodyportion of the call; and secure the lat- RUTH E. ELSHEIMER, ter to theshoe. H. A. CONSTANTINE.
